Elizabeth and John Proctor fight in the beginning scene of Act II. Their fighting is about the fact that John met Abigail alone in Act I. John ends up assuring Elizabeth that he is loyal to her and wants to please her in any way possible.
Later in Act II Elizabeth and John are outside talking when their servant named Mary whcih gave Elizabeth a poppet with a needle hidden within it. With this meeting, Mary lets the two know that Elizabeth's name is going around in court that she might be a witch. This claim meant to John that Abigail wanted revenge on him for being with Elizabeth instead of her.
In the next scene the viewer sees that the Judges from the Mississippi court went to Salem. They decide that if witchery is happening in Salem that they will push it out.
Next there is a long sequence of people getting blamed by the afflicted girls which ends up leading to many people ending up in jail and on death row.
Reverend Hale ends up visiting the Proctor household and enters their house to find things relating to their faith. When inside he states that they rarely have been to Sunday chruch meets and that their latest child is not baptized. Also, Reverend Hale finds out that John does not know his commandments. Regardless of this evidence he seems to want to trust the Proctors anyways.
Reverend Hale with John and Elizabeth step outside and find that the judges are taking in a group of people by chained carriage because they were accused of being a witch. Then Elizabeth's arrest is stated which then leads to a search of the house. When they are searching they find evidence to arrest when they find the poppet with a needle in it, and that Abigail had a needle in her stomach the same day. They end up taking away Elizabeth, and after they leave John tells Mary that she must testify in court because it was the truth.
